Significance Of Neonatal Umbilical Arterial Blood Gas Analysis In Neonatal Asphyxia

Objctives:The relationship between the umbilical arterial blood gas and the Apgar score was analyzed,and the clinical significance of umbilical arterial blood gas analysis in the diagnosis of neonatal asphyxia and multiple organ injury was investigated.Methods:72 newborns born in our hospital from June 2013 to June 2018 were selected as subjects.All newborns were divided according to the Apgar score.There were 40 newborns(8~10 points)in the normal group and 32 cases(?7 points)in the asphyxia group,including 24 cases(4~7 points)in the mild asphyxia group.Asphyxia group 8 cases(0~3 points).Umbilical arterial blood gas analysis was performed immediately after birth in all newborns,and pH values,Pco2 values and Po2 values of cord blood in all newborns were recorded,and all newborns should be examined for organ damage after birth.Data were collected and the relationship between the 1 min Apgar score at birth and the umbilical arterial blood gas analysis at each birth,and the relationship between umbilical arterial blood pH and organ damage were analyzed.Results:(1)The gender,weight and the mode of delivery of pregnant women in each group were not statistically significant(P>0.05),which was comparable.(2)The pH value and PO2 value of umbilical arterial blood in the three groups of neonates decreased with the decrease of 1min Apgar score;PCO2 increased with the decrease of Apgar score,and the difference between the two groups was statistically significant(p<0.05).(3)There were significant differences in blood gas pH values between the three groups(P<0.05).With the increase of asphyxia,neonatal acidosis was also aggravated.The pH value of the newborn group was compared with the mild asphyxia group and the severe asphyxia group.The pH value of the mild asphyxia group was compared with the severe asphyxia group.Learning differences(p<0.05).(4)With the decrease of Apgar score,the incidence of organ injury increased gradually in the three groups of newborns.There was a statistically significant difference between the different groups(p<0.05).The incidence of organ injury in severe asphyxia group was significantly higher than other groups.With the decrease of pH value of umbilical arterial blood,especially at pH<7.00,the incidence of neonatal organ injury increased significantly,while the difference was statistically significant(p<0.05).Conclusions:Umbilical arterial blood gas analysis and Apgar score can be used for the diagnosis of neonatal asphyxia and organ damage,while umbilical arterial blood gas analysis,especially pH value in the diagnosis of neonatal asphyxia and organ damage than Apgar score objectivity Stronger,so if you combine the two,you can more intuitively reflect the cause of low scores in newborns and the degree of ischemia and hypoxia,which is conducive to improving the accuracy of neonatal asphyxia diagnosis and reducing the rate of misdiagnosis for clinical care.The staff can provide effective reference and guidance when performing neonatal asphyxia resuscitation and rescue,which can effectively reduce the lethality and disability rate of newborns and play an important role in improving the quality of life of newborns.
